Abstract In order to explore the characteristics of rockburst acoustic signals，laboratory experiment was conducted to simulate the process of granite rockburst using the true-triaxial rockburst test system developed in-house. The acoustic signals were monitored during the rockburst process. The characteristics of waveform，spectrum and fractal of acoustic signals of rockburst process were studied. The results showed that the variation characteristics of waveform reflected the main failure process of rockburst. In the rockburst process，a relatively quiet period of the acoustic signals，i.e.，the amplitude of waveform becoming quite low close to the moment of rockbursting was discovered. Furthermore，the value of time fractal dimension of amplitude declined continuously to the lowest value after increased to a peak during a period of time can be regarded as an indication of rockburst. During the process of rockburst，different failure phenomena have different spectrum features，the main frequency value of acoustic signals has a tendency of changing from high to low，the spectrum form experience an alternating process of multimodal and unimodal. In conclusion，acoustic signals in rockburst process have distinct characteristics and inner evolution laws on waveform，time fractal dimension of amplitude and frequency spectrum. Therefore，the acoustic signals can be regarded as the precursor information for rockburst prediction.

Key words： rock mechanics rockburst acoustic signal fractal spectrum analysis
